+## 🧪 Testing
+
+### Test Setup
+
+The project includes comprehensive backend testing using **xUnit** and **Moq** for .NET 9.0.
+
+#### Prerequisites
+
+- **.NET 9 SDK** (required for running tests)
+- **PostgreSQL** (for integration tests, can use in-memory database for unit tests)
+
+#### Test Project Structure

+
+### Running Tests
+
+#### Run All Tests
+
+```bash
+cd server
+dotnet test Tests/server.Tests.csproj --configuration Release --verbosity normal
+```
+
+#### Run Tests with Coverage
+
+```bash
+cd server
+dotnet test Tests/server.Tests.csproj \
+  --configuration Release \
+  --collect:"XPlat Code Coverage" \
+  --results-directory:./coverage
+```
+
+#### Run Specific Test Class
+
+```bash
+dotnet test Tests/server.Tests.csproj --filter "FullyQualifiedName~AccountControllerTests"
+```
+
+#### Run Specific Test Method
+
+```bash
+dotnet test Tests/server.Tests.csproj --filter "FullyQualifiedName~AccountControllerTests.Register_WithValidData_CreatesUser"
+```
+
+### Test Results
+
+#### Current Test Status
+
+✅ **All Tests Passing**: 117 tests, 0 failures
+
+#### Test Coverage by Category
+
+**Controller Tests (6 test classes, ~40 tests)**
+
+- ✅ `AccountControllerTests` - Authentication, registration, profile management
+- ✅ `VaultControllerTests` - Vault CRUD, member management, invites, policies
+- ✅ `VaultItemControllerTests` - Item CRUD, permissions, restore operations
+- ✅ `NotificationControllerTests` - Notification retrieval, marking as read, deletion
+- ✅ `ContactControllerTests` - Contact form submission
+- ✅ `HealthControllerTests` - Health check endpoints
+
+**Service Tests (8 test classes, ~77 tests)**
+
+- ✅ `TokenServiceTests` - JWT token generation, validation, refresh tokens
+- ✅ `VaultServiceTests` - Vault business logic, permissions, CRUD operations
+- ✅ `VaultServiceExtendedTests` - Advanced vault operations (invites, transfers, policies)
+- ✅ `VaultItemServiceTests` - Item operations, permissions, encryption
+- ✅ `VaultItemServiceExtendedTests` - Advanced item operations (restore, permissions)
+- ✅ `NotificationServiceTests` - Notification creation, retrieval, updates
+- ✅ `EncryptionServiceTests` - AES-256 encryption/decryption, Unicode support
+- ✅ `DeviceServiceTests` - Device fingerprinting, verification, management
+
+### CI/CD Integration
+
+Tests are automatically run in **GitHub Actions** on every push and pull request:
+
+```yaml
+# .github/workflows/ci.yml
+- name: Run tests
+  run: dotnet test server/Tests/server.Tests.csproj --no-restore --configuration Release --verbosity normal
+```
+
+#### Test Execution in CI
+
+- **Trigger**: Push to `main`, `develop`, `master` branches or pull requests
+- **Environment**: Ubuntu Latest with .NET 9.0.x
+- **Test Results**: Uploaded as artifacts for review
+- **Status**: All tests must pass for CI to succeed
+
+### Test Architecture
+
+#### Test Patterns Used
+
+1. **Arrange-Act-Assert (AAA)**: Standard test structure
+2. **Mocking**: Moq framework for dependencies (database, external services)
+3. **In-Memory Database**: EF Core InMemory provider for fast unit tests
+4. **Test Fixtures**: Reusable test data and setup helpers
+5. **Integration Tests**: Full controller tests with mocked services
+
+#### Example Test Structure
+
+```csharp
+[Fact]
+public async Task Register_WithValidData_CreatesUser()
+{
+    // Arrange
+    var registerDto = new RegisterDTO { /* ... */ };
+
+    // Act
+    var result = await _controller.Register(registerDto);
+
+    // Assert
+    Assert.NotNull(result);
+    Assert.Equal(200, ((ObjectResult)result).StatusCode);
+}
+```
+
+### Test Data Management
+
+- **Test Helpers**: `TestHelpers.cs` provides utilities for creating test data
+- **Isolated Tests**: Each test is independent with its own database context
+- **Cleanup**: Automatic cleanup after each test execution
+- **Test Data**: Realistic test scenarios covering edge cases
+
+### Coverage Goals
+
+- ✅ **Controllers**: 100% endpoint coverage
+- ✅ **Services**: Core business logic fully tested
+- ✅ **Critical Paths**: Authentication, authorization, encryption
+- 🔄 **Integration Tests**: API endpoint integration testing
+- 🔄 **E2E Tests**: Full user workflow testing (planned)
+
+### Running Tests Locally Before Push
+
+Always run tests locally before pushing to ensure CI passes:
+
+```bash
+# Run all tests
+cd server
+dotnet test Tests/server.Tests.csproj --configuration Release
+
+# Expected output: All 117 tests passing ✅
+```
